CAT Mock Test - 13 (November 15) - Question 1

Directions: The passage below is accompanied by a question. Choose the best answer to the question.

Where there is a rule, there is also a violation of this rule. In a society regulated by laws, such a violation is called a crime. For centuries, crimes were among the major problems for societies to solve; criminals were detained, isolated, and punished - with varying severity - but it did not help to eliminate or prevent crime. As if this is not enough, in many countries, the problem of crime poses yet another challenge to both law enforcement systems and society in general - and this challenge is juvenile delinquency. It is more or less clear what to do with grown-up criminals: the range of actions against them varies from correctional labour to capital punishment, and is generally well thought out and adjusted. However, in the case of juvenile criminals, it is often unclear which punishment is appropriate, what causes underage individuals to commit crimes, and what are the ways to prevent it. There are, however, numerous theories regarding these questions.
The most obvious and widely discussed factor leading to juvenile delinquency is the surroundings in which children grow up. If the environment is not suitable, not contributing to a child's moral and intellectual development, he or she may grow up with a lack of strong moral guidance. One of the main constraints holding an individual from committing crimes is not obedience to the law, but rather the moral, ethical, the immanent understanding of what is right and what is wrong; usually, this develops under the influence of parents and beneficial surroundings such as friends, authoritative social groups, and so on. However, if there is little-to-no positive influence, children tend to develop moral poverty: the incapacity to control their behaviours guided by the aforementioned skills and principles.
Although the majority of sociologists and criminologists agree on the importance of the environment in which an individual grows up, there are more debated impacts causing juvenile delinquency. One of them is the influence of video games and other media such as music or TV programmes. It is true that contemporary media is filled with violence, sexual content, exploitation, and stereotypes. But it is doubtful that it can cause a mentally and morally healthy child from a normal family to cross the line and commit a crime.
What can, however, cause a morally stable juvenile to commit a crime is drugs. It becomes clear that in order to prevent or decrease juvenile delinquency, it is not enough to encourage parents to simply establish a stricter control over their children - doing so would be shifting responsibility from the whole society to its separate members. What parents can do, however, is try to keep their children away from dangerous substances; it is important to remember that although a teenager cannot be helped from rebelling (since this process is natural and caused by both mental and hormonal factors), he or she can be at least guided towards a more healthy rebellion: for example, skateboarding or street art instead of smoking marijuana.

Q. Which of the following statements can be inferred from the passage?

Detailed Solution for CAT Mock Test - 13 (November 15) - Question 1

According to the passage, 'If the environment is not suitable, not contributing to a child's moral and intellectual development, he or she may grow up with a lack of strong moral guidance. One of the main constraints holding an individual from committing crimes is not obedience to the law, but rather the moral, ethical, the immanent understanding of what is right and what is wrong; usually, this develops under the influence of parents and beneficial surroundings such as friends, authoritative social groups, and so on.

Although the majority of sociologists and criminologists agree on the importance of the environment in which an individual grows up, there are more debated impacts causing juvenile delinquency.' Therefore, option 1 is the right answer.
The opposite of option 2 is asserted in the passage.
Option 3 says that parents are the only influence; whereas other influencing factors are also mentioned.
Option 4 is not correct as a differing opinion in expressed in the passage.

CAT Mock Test - 13 (November 15) - Question 2

Directions: The passage below is accompanied by a set of questions. Choose the best answer to each question.

When we are not actually holding them, books are things over which we like to wring our hands. They stand, in their very solidity, for what might be precarious and endangered in our brave newish world. Worries about the accelerated pace of everyday life, the diminution of attention spans, and the eroded boundary between work and leisure all animate—and get entangled in—the familiar lament over what Sven Birkerts called, in the subtitle of his 1994 book, the "fate of reading in an electronic age." We sense that we don't read quite the way we used to, and that it matters.
Against the backdrop of the current cultural complaints, Christina Lupton, who teaches English literature at the University of Warwick, turns her attention to England during roughly the second half of the 18th century in an effort to explore the relationship between reading books and spending time. This historical move is unsurprising, not only because that's where Lupton's scholarly and critical expertise lies but also because the era of Enlightenment in Western Europe has been the most frequent landing spot for book historians and media theorists looking for precedent dislocations of the written word that, today, are produced by electronic text transmission and the internet.
Rather, it is that she presents a set of exemplary readers and writers whose reflective encounters with books highlight the utility of the codex as a technique for thinking about time in its many meanings. The result is a vigorous and partially novel defense of the value of books and the humanities to a happy and meaningful life. Whether these approaches to books are aligned, competing, or loosely affiliated variations on the single theme of time seems open to debate. But Lupton links them all because they fly in the face of received wisdom about books and of ideologically dominant attitudes toward time use. Printed books, both their critics and their beleaguered defenders tend to agree, promote linear and sequential thinking by stabilizing, sequestering, and ordering their contents between their covers. Somewhat analogously, it is typical to describe modern time as linear, uniform, and homogeneous. Lupton encourages us to see both books and temporal experience differently. Rather than seeing time as a scarce, homogeneous resource to be economised or optimised, Lupton invites us to follow her in seeing books as things that introduce difference, discontinuity, and even plasticity into time itself.
Reading and the Making of Time says relatively little about two qualities of bound books that stand out in our age of screen reading: their heft and their suitability for display. The bulkiness and weight of books, from which Kindles and Nooks promise liberation, remain, for many readers, central to their talismanic potential, as do so many other tactile variables related to page texture or the flexibility of covers and binding.
Students entering my office sometimes inquire whether I've read all the thousands of books that line its walls. In the wake of Christina Lupton, I might expect them to ask whether I aspired to read all these books. But whether books represent our past experiences or our dreams for the future, the way we showcase and arrange them seems interesting in an age in which databases and search engines have eclipsed books as tools for looking things up. Displayed books gesture forward and backward to acts of reading and rereading; of purchasing, posing, moving, and unpacking; of passing time and dropping into its folds.

Q. The passage is primarily concerned with which of the following?

Detailed Solution for CAT Mock Test - 13 (November 15) - Question 2

The author reiterates that books are related to our past and our future and can be revisited multiple times differently. Therefore, option 3 is the right answer. Option 1 and 2 rather take a negative turn and focus on what is not the main idea of the text. Option 4 is incorrect because it incorrectly states that 'understanding multiple ways of time' is the main focus.

Detailed Solution for CAT Mock Test - 13 (November 15) - Question 3

According to the passage, 'But whether books represent our past experiences or our dreams for the future, the way we showcase and arrange them seems interesting in an age in which databases and search engines have eclipsed books as tools for looking things up. Displayed books gesture forward and backward to acts of reading and rereading; of purchasing, posing, moving, and unpacking; of passing time and dropping into its folds.' This proves that option 1 is the right answer.
Although the author states what is given in option 2, it is not what the author tends to point towards through the use of example of his office. Option 3 is incorrect because it takes the meaning too literally. The author states it as a question that he would like to be asked or the perception that he would like his students to develop - not keeping books down after just one read. Option 4 is incorrect because it is neither implied in the text nor what the author intends to explain through the example of his office.

CAT Mock Test - 13 (November 15) - Question 4

Directions: The passage below is accompanied by a set of questions. Choose the best answer to each question.

The young scientist in India is an endangered species. The threat comes from the predatory habits of a more evolved species that is the senior scientist. An Indian university teacher in a letter to the international science journal Nature wrote plaintively: ''Thesis supervisors take undue credit for the work of their protégés''. A young scientist needs the goodwill and support of the scientist-in-power at every step: for completion and continuation of his work, for participation in national and international meetings and research projects, for recognition and reward and for promotion. This support is available but at a price. The price often is the sharing of credit. A worthwhile research paper or a project originating from a humble scientist would often end up with the scientist-in-power as the principal author or investigator.

The power of the senior scientist over his junior stems from the fact that science is the only profession in the world which is self-assessing. Unlike in the bureaucracy or the military where the top authority vests with non-professionals, a scientist's work can be overseen and evaluated only by fellow scientists.

Fortunately for the scientists, support for science is a badge of honour for nations aspiring to modernity. That is why the government which normally would not pay the piper unless it can call the tune, happily makes an exception in the case of science. Society values continuity, stability and security, and turns to the past for guidance and support. Science, on the other hand, aspires to instability. It aims at creating something that did not exist before. It seeks a break with the past with an eye on the future.

It is an irony that in today's world, feudalism can be sustained only in the administration of a modern scientific research centre. One must, however, not be unfair to the feudal lords of yesteryears whose conduct had the sanction of the times. Neo-feudalism is pernicious because it is anachronistic; it can be sustained only by a subversion of the system in the hands of the people who are entrusted with the task of upholding it.

If we define professionalism as the realisation that an institution ranks higher than an individual and that the collective goal is more important than individual ego, it must be admitted that we are unprofessional people. It is wrong in principle to give any individual a larger-than-the-institution image. This philosophy becomes all the more debilitating, because recently there has been an alarming decline in the quality of leadership in science as in other walks of life. It is relatively speaking an easy matter to evaluate a leader. His commitment can be judged by asking whether he is giving to the system or taking from it. The calibre of a leader can be gauged from the calibre of the people willing to play second fiddle to him.

Under these circumstances, if a chief executive is to be projected as the master of an institution rather than its servant, this can be done only by degrading the institution. It will be like a cinema hall whose facade remains the same, but the posters outside and the picture inside go on changing.

Detailed Solution for CAT Mock Test - 13 (November 15) - Question 6

1. Correct. The passage states, "Neo-feudalism is pernicious because it is anachronistic; it can be sustained only by a subversion of the system in the hands of the people who are entrusted with the task of upholding it." The next few lines state that an Indian scientist is comfortable among his protégés and mentors and not among peers. This feudal system as described is non-professional and harms or destroys the system. Thus, option 1 is the correct answer.
2. Incorrect. This option paints the feudal lords in a negative light while the text states "One must, however, not be unfair to the feudal lords of yesteryears whose conduct had the sanction of the times." Hence, incorrect.
3. Incorrect. Although true, this is not stated as the reason in the passage why 'neo-feudalism' is pernicious.
4. Incorrect. This is not the reason that the author terms neo-feudalism as 'pernicious' in the passage.

CAT Mock Test - 13 (November 15) - Question 7

Directions: Read the following passage carefully and answer the given question.

There is a history of intimate links between the study of dreams and the US advertising industry. Sigmund Freud's nephew Edward Bernays is credited with pioneering the US public relations and advertising industries, in part through influential books such as Propaganda (1928). It was Freud's theories, which examined the nature of dreams and the unconscious, that Bernays took as inspiration for his approaches to influencing the public, with a focus on the creation of unconscious desires and associations. In a series of hugely successful advertising campaigns, Bernays demonstrated that the irrational forces that drive human behaviour could be harnessed to 'engineer consent' and manipulate people's behaviour without their realising it. It is psychoanalysis that gave advertising the idea to sell by association, linking cars and masculinity or cigarettes and freedom, just as the Coors dream-incubation project linked beer with positive, refreshing experiences.
Bernays inspired a wave of advertising industry leaders in the ensuing decades to hire 'motivational analysts' and 'depth manipulators', who sought to uncover and redirect the unconscious desires of consumers. The use of subliminal stimuli, first explored in perception and attention laboratories, seemed well suited to their purposes. Research suggested subliminal stimuli might be able to deliver messaging below a person's perceptual threshold, allowing for the undetected insertion of new motivations and meaningful associations in vulnerable viewers.
In 1957, a press conference from the market researcher James Vicary – claiming that flashing the phrases 'Eat popcorn' and 'Drink Coca-Cola' during a film significantly increased the sale of these products – hit a raw nerve. Claims about the potential of subliminal messaging smacked of manipulation by a Communist state broadcast. A demonstration of subliminal advertising was demanded and held for the Federal Communications Commission (FCC) and members of Congress, where 'Eat popcorn' was flashed at the attendees during a TV programme. But the response was mild: one senator reportedly quipped 'I think I want a hot dog,' and it seems that nobody was overcome with a desire for popcorn.
It's not surprising that the audience was unmoved; the evidence for large behavioural effects caused by subliminal advertising was, and remains, quite weak. By his own admission (five years after the fact), Vicary had faked his study. Nevertheless, the FCC has stated that: 'Regardless of whether it is effective, the broadcast of subliminal material is inconsistent with a station's obligation to serve the public interest because it is designed to be deceptive.' In the view of the regulatory body, a message that seeks to circumvent the awareness of a listener to influence them without their being able to assess it is, by nature, deceptive. More generally, the Federal Trade Commission, which has the power to regulate all advertising, has concluded that: 'It would be deceptive for marketers to embed ads with so-called subliminal messages that could affect consumer behaviour,' making it a prohibited form of advertising. But no extension of these prohibitions to dream hacking has been made, and the advertising industry must be aware of this lack.

Q. Which of the following does the author imply when he mentions the importance of delivering a message 'below a person's perceptual threshold' in the second paragraph?

Detailed Solution for CAT Mock Test - 13 (November 15) - Question 7

The importance of delivering such message below a person's perceptual threshold is to generate consent unconsciously. People are not willing to otherwise being manipulated. When an intended message is inserted below the consumers' perceptual threshold, the consumers are not fully able to comprehend it but feel that their consent is necessary to satisfy their wants.

Option 1: This is not inferable. No such comparison between explicit advertising or implicit marketing is being made.
Option 3: Nothing can be inferred about the relative effectiveness of subliminal stimulus under different situations. Although helpful, such low threshold cannot be inferred as most effective.
Option 4: Nothing can be inferred in this regard.

Q. According to the passage, why did James Vicary's claim about the effectiveness of subliminal advertising 'hit a raw nerve'?

Detailed Solution for CAT Mock Test - 13 (November 15) - Question 8

'Hit a raw nerve' is to provoke a reaction. Here, the text states that the government came into action when they heard the market researcher claiming the effects of subliminal messaging. The government perceived it as 'manipulation by a Communist state broadcast'.

Option 1: No such inference can be made. People were indeed able to comprehend the effectiveness of such strategy, which eventually led to inquiries into such advertising strategy.
Option 2: '...subliminal advertising was seen as "a threat" to the dominance of traditional advertising industry' makes this option incorrect.
Option 3: This is the best possible inference as the passage mentions about the fear of manipulation by a Communist state broadcast and also that demonstrations were held for FCC and the Congress. The last paragraph also talks about the steps taken by FCC in this regard.
Option 4: Such different results occurred afterwards when an enquiry into the effectiveness of subliminal advertising was made. It was not the cause of hitting the nerve, but an effect.

CAT Mock Test - 13 (November 15) - Question 9

Directions: There is a sentence that is missing in the paragraph below. Look at the paragraph and decide in which blank (option 1, 2, 3, or 4) the following sentence would best fit.

Sentence: The aesthetic realm sits, rather, askance to politics; it allows us to attend to politics but relieves us from the weight of taking on a political position.

Paragraph: Art, perhaps uniquely among the forms of political discourse available to us, allows for audiences to contemplate issues at the heart of political clashes, while temporarily suspending the judgment of right and wrong. ___(1)___. The space of aesthetics is therefore neither fully political nor anti-political. ___(2)___. None of this is to suggest, of course, that this aesthetic, inconclusive mode is better than either objectivity or activism. ___(3)___. Instead, the suggestion is that the democratic public sphere requires a plurality of these different modes of discourse, among which the arts play their distinctive role. ___(4)___.

Detailed Solution for CAT Mock Test - 13 (November 15) - Question 9

The given sentence best fits blank 2. The sentence preceding blank 2 states that the space of aesthetics is neither fully political not anti-political. The given statement then elaborates this view by explaining 'why' the author regards the space of aesthetics as neither fully political nor anti-political. In the line following the blank, 'this inconclusive mode' specifically refers to the nature of aesthetics described in the previous statements. Option 3 is incorrect as both the following and the preceding statements connect without the blank. 'These different modes' refer to 'objectivity or activism' in the previous statement. The statement also does not fit as the conclusion of the passage (blank 4). Blank 1 is also misplaced, as the statement following the blank serves as a deduction made from the statement preceding the blank. Thus, the gap is redundant.

Paragraph: Data centres differ based on their technological sophistication: there is a tiering system that ranks centres according to their resources, scale of operation, and level of redundancies. ___(1)___. Only about one-third of the world's data centres resemble the oft-circulated images of Google's idyllic facilities, glittering with colourful pipes and smiling technicians who get around their workplaces on scooters. ___(2)___. The remaining two-thirds of data centres are far less impressive. Some are found in mouldy basements, others in the shells of decaying office buildings or abandoned military installations. ___(3)___. As such, the workers in these facilities must rely more readily on their experiences and finely tuned instincts to keep their patches of the cloud 'up', however imperfectly. ___(4)___. They do not see themselves as automatons, as mere cogs in a perfectly optimised machine, but rather as hunters, firefighters or even priests, who must make, find or invent ways to meet the impossible demand of an unremitting cloud.

Detailed Solution for CAT Mock Test - 13 (November 15) - Question 10

The given sentence best fits blank 3. The phrase 'outdated, energy-inefficient designs' links with 'shells of decaying office buildings or abandoned military installations' in the sentence preceding the blank. The sentence following the blank presents the outcome of data companies using outdated designs, that is the workers of these facilities relying more their own experiences. Blanks 1 and 2 are redundant as all statements link with each other. The first line describes how data centres differ, and the next two statements go on to explain this difference (one-thirds, two-thirds, etc.). Option 4 is also incorrect, as 'they' in the last sentence directly refers to 'workers' in the second last sentence.

CAT Mock Test - 13 (November 15) - Question 11

Directions: Answer the question on the basis of the information given below.

In a prestigious scholarship selection process, a committee comprised of professors and professionals came together to evaluate and award scholarships to exceptional students. The committee members were Andrew, Benjamin, Claire, David, Emily, and Fiona. Every committee member individually interviewed each of the students individually and awarded a recommendatory card only if he found him to be truly deserving. The card recommendation value was denoted as 2, 3, 7, 13, 17 or 19. Each interviewer awarded card of a single recommendation value only. Upon the completion of all interviews for a candidate, the scholarship amount awarded was determined by multiplying the card recommendation value they received by a factor of 100. For example, if a candidate card recommendation values are 7, 13, and 17, their total scholarship amount would be Rs. 100 × (7 × 13 × 17) equaling Rs. 1,54,700. Among the brilliant recipients of scholarships, let's consider the following five students: Grace, Henry, Isabella, Jacob, and Katherine. The scholarships they were granted, in ascending order, were Rs. 13,300, Rs. 71,400, Rs. 1,72,900, Rs. 9,28,200, and Rs. 12,59,700, respectively. Now, let's explore some additional facts about the selection process:
(i) Emily awarded cards to all the candidates except Katherine and Jacob.
(ii) Benjamin granted cards to all except Grace.
(iii) Isabella received the second lowest number of cards.
(iv) Among Andrew, Claire and Fiona, no one awarded any card to Isabella.
(v) David chose to award a card to Katherine but not to Henry.
(vi) Claire decided to bestow a card upon Jacob but not Katherine.

Q. Emily did not award cards to which of the following groups?

Detailed Solution for CAT Mock Test - 13 (November 15) - Question 11

Y represents cards awarded.
N represents cards not awarded.
Emily awarded cards to all the candidates except Katherine and Jacob.

Benjamin granted cards to all except Grace.

Isabella did not receive any cards from Andrew, Claire and Fiona.

David chose to award a card to Katherine but not to Henry.
Claire decided to bestow a card upon Jacob but not Katherine.


From the above table, the second lowest number of cards = 3 (7, 13, 19)
Isabella received the second lowest number of cards, so Isabella must receive cards from David.
Also, Isabella scholarship would be 1,729 (in hundreds).

Isabella received cards from Benjamin, David and Emily and the card recommendation values are 7, 13 and 19. So, Andrew, Claire and Fiona have different recommendation values other than 7, 13 and 19.
Benjamin awarded cards to all except Grace and only 7 is common in 4 students.
Hence, Benjamin had a card of recommendation value 7.


From the above table, the card recommendation values 13 and 19 are common in Grace and Isabella, so David must have awarded a card to Grace and the card recommendation value of David and Emily will be either 13 or 19.


In the above given table, 13 and 19 both occur 3 times.

Katherine must have cards of recommendation values 7 and 13 or 19. From the table, the only possible recommendation values of cards of Katherine will be 7 and 19.

19 is common in Grace, Isabella and Katherine, so David had a card of recommendation value 19.

From the above table, the 13 recommendation value card is available in Henry, Grace and Isabella and 13 occurs 3 times, so Henry's card recommendation values will be 2, 3, 7, 13, and 17 and the remaining will be of Jacob.


17 occurs three times and is common in Henry, Grace and Jacob, so Claire had a card recommendation value of 17.

CAT Mock Test - 13 (November 15) - Question 12

Directions: Read the following and answer the question.

Mr. Ernest who likes to play cards has eleven cards available – C1 through C11 with him. Among these eleven cards, there are five different colors of cards – Red, Blue, Yellow, White and Black – such that there are exactly three Red cards, two Blue cards, two Yellow cards, two White cards and two Black cards. The Mr. Ernest picks the six cards such that any game contains exactly two Red, one Blue, one Yellow, one White and one Black. The Mr. Ernest picked the following cards combinations for different games:

Q. If C2 is a Yellow card and C8 is a White card, which among the following is a Black card?

Detailed Solution for CAT Mock Test - 13 (November 15) - Question 12

From the games given above, we can see that

If C1 is in a game, then C10 and C11 are not in the game.

If C2 is in the game, C6 is the only card which is not in the game.

If C3 is in the game C4 and C8 are not in the game.

If C4 is in the game, C3 and C11 are not in the game.

If C5 is in the game, no card is out of the game.

If C6 is in the game, C2 and C11 are the only cards not in the game.

If C7 is in the game, no card is out of the game.

If C8 is in the game C3 and C11 are not in the game.

If C9 is in the game, C11 is the only card not in the game.

If C10 is in the game, C1 is the only card not in the game.

If C11 is in the game, C1, C4, C6, C8 and C9 are not in the game.

For C5 and C7, no one is out of the game when they are part of the game.

This is possible only if they are both Red cards.

If they are of any other color, at least one card must not be in the game with them.

For each of the other colors, two cards are available, out of which one is selected. Hence, for each of the other colors, if one of the two cards is present the other must definitely not be present. Since this is not the case for each of C5 and C7, they must be Red.

In game 2 and game 4, both C5 and C7 are present. Hence, any card which is part of these two games cannot be Red.
Therefore, C1, C2, C3, C6, C9, C10 and C11 cannot be Red. This means one of C4 and C8 is the third Red card.

Since C2 is not a Red, C2 must be of a color in which there are exactly two cards. If C2 is in the game, one of the other cards (which Is of the same color as C2) must definitely not be in the game. If C2 is in the game, C6 is the only one which is not in the game. Hence. C2 and C6 must be of the same color. (Consider the case that C2 and C6 are of different color. In this case, C2 is in the game with everyone else except C6. Hence, none of them can be the same color of card as C2.)
Similarly. if C9 is part of the game, C11 is not a part of the game. Hence, C9 and C11 must be of the same color.
If C10 is in the game, C1 is not in the game. Hence, C10 and C1 must be of the same color.
The third Red can only be C4/C8.
If C4 is the third Red card, C3 and C8 must be of the same color.

If C8 is the third Red card, C3 and C4 must be of the same color.

Therefore, the following combinations are possible: (C1, C10); (C9, C11); (C2, C6); (C3, C4/C8); (C5, C7, C8/C4)

Cards which were picked in three games are C5, C7 and C9. Of these three, C9 is the only card which can be a Black (as C5 and C7 are Red). If C9 is a Black, C11 must also be a Black.

CAT Mock Test - 13 (November 15) - Question 13

Directions: Answer the question on the basis of the information given below.

A placement exam comprises six parts viz. Part-A, Part-B, Part-C, Part-D, Part-E and Part-F, not necessarily in the same order. A student who takes the exam attempts each of the six parts, one after the other. The order in which any student completes the six parts is the same for all the students.
Six students—James, Benjamin, Albert, Thomas, Anderson and George - attempted the placement exam, which started at exactly 09:30 on a particular day. The table below provides the part that each student was attempting in at exactly 09:40 and 09:45.

(a ''X' in a table indicates that none of the students were attempting in that part at that time).

Q. What was the fourth part of the placement exam?

Detailed Solution for CAT Mock Test - 13 (November 15) - Question 13

Since the students attempt in parts in the order, we can determine the order of the parts by observing the parts that each student attempted at 09:40 and 09:45.
James attempted Part-C before Part-F. Hence, Part-C is before Part-F.
Benjamin attempted Part-E before Part-B. Hence, Part-E is before Part-B.
From Albert, we can observe that Part-B is before Part-C.
From Thomas, we can observe that Part-D is before Part-A.
From Anderson, we can observe that Part-A is before Part-E.
From George, we cannot infer anything as he was in the same part.
Combining the information from James and Albert, we can see that Part-B is before Part-C, which, in turn, is before Part-F.
Combining this with information from Benjamin, we can see that Part-E is before Part-B.
Combining this with information from Thomas, we can see that Part-D is before Part-E.
From Anderson, we get that Part-A is before Part-E. Hence, Part-A is before Part-E, Part-B, Part-C, and Part-F.
Therefore, between Part-A and Part-D, one of the two is first and the other is second. We can fix the order of the other four parts.
The following table provides the possible orders of the six parts:

The fourth part of the placement exam was Part-B.

CAT Mock Test - 13 (November 15) - Question 19

A man invested Rs. 80000 in a bond which gives 10% p.a interest compounded half yearly. If the annual rate of interest is increased by 10% at the end of every half year. What will be the interest earned (in Rs.) for one and a half years?


Detailed Solution for CAT Mock Test - 13 (November 15) - Question 19
  • The rate of interest given to us = 10% p.a
  • So, rate of interest for half year = R/2 = 5%
  • Now as the rate of interest increases every half year, hence 2nd year it will be = 15%
  • and the next year it will be = 25%
  • Hence, the amount per year is calculated below given that the principal = 80,000
  • The required interest that has been accrued is 40,750
CAT Mock Test - 13 (November 15) - Question 20

If the ratio of the ages of two friends A and B are in the ratio 3 : 5 and that of B and C is 3 : 5 and the average of their ages 15 years earlier was 34, then how old will be B after 20 years from now?

Detailed Solution for CAT Mock Test - 13 (November 15) - Question 20
Ratio of ages of A and B = 3:5 = 9:15.

Ratio of ages of B and C = 3:5 = 15:25

Ratio of ages of A, B and C = 9:15:25.

15 years earlier their average age was 34 years.

Present average = (34+15) years = 49 years

Present sum = 49 X 3 years = 147 years.

A's age = (9/49) x 147 years = 27 years

B's age = (18/49) x 147 years = 45 years

C's age = (25/49) x 147 years = 75 years

After 20 years, B's age is 65 years.

CAT Mock Test - 13 (November 15) - Question 22

A bag contains 5 Red, 4 Green and 3 Blue balls. Three balls are drawn from the bag at one go. What is the probability that not all the three balls drawn are of the same colour?

Detailed Solution for CAT Mock Test - 13 (November 15) - Question 22

Three balls can be drawn from a total of 12 balls in 12C3 ways.

Probability that all three balls are of same colour = (5C3 + 4C3 + 3C3)/12C3

= (10 + 4 + 1)/220

= 15/220

= 0.068

Hence Probability that all three balls drawn are not of the same colour is = 1 - 0.068 = 0.932

CAT Mock Test - 13 (November 15) - Question 23

If log9(3log2(1 + log3(1 + 2log2x))) = 1/2, find x.


Detailed Solution for CAT Mock Test - 13 (November 15) - Question 23

log9(3log2(1 + log3(1 + 2log2x))) = 1/2
3log2(1 + log3(1 + 2log2x)) = 91/2 ( logaX = b means X = ab)
3log2(1 + log3(1 + 2log2x)) = 3
log2(1 + log3(1 + 2log2x)) = 1
1 + log3(1 + 2log2x) = 2
log3(1 + 2log2x) = 1
1 + 2log2x = 3
2log2x = 2
log2x = 1
x = 2

CAT Mock Test - 13 (November 15) - Question 24

Glucose solution containing 6% glucose and rest water, is mixed with water. One third ofthe quantity of the solution obtained is drained out and replaced by juice which has 10% fruit concentrate and rest water. If water now accounts for 94% of the total solution, what isthe ratio of glucose and fruit concentrate?

Detailed Solution for CAT Mock Test - 13 (November 15) - Question 24
We start at the stage when one third of the solution is removed and replaced with fruit concentrate solution. Assume that the fruit concentrate solution is 100 ml in quantity, which is one third of the total solution so total solution must be 300 ml in volume. Also 10% i.e. 10 ml of this fruit concentrate solution added should be fruit concentrate. So the final solution has 10 ml of fruit concentrate. Also since final solution contains 94% water, which is 94 X 3 = 282 ml. Out of 300 ml, 282 ml is water and 10 ml is fruit concentrate, so glucose should be 300 - 282 - 10 = 8 ml. Required ratio therefore is 8 : 10 or 4 : 5.
CAT Mock Test - 13 (November 15) - Question 25

CAT Mock Test - 13 (November 15) - Question 26

Ritesh invested one half of his money in an investment instrument that gave him simple interest for 2 years and he got Rs.680 as interest. He invested the remaining of his money in another investment instrument that gave him compound interest with interest being compounded annually, at the same rate of interest, for the same 2 years and he got Rs.730 as interest. What was the approximate total money invested by him in these two instruments?

Detailed Solution for CAT Mock Test - 13 (November 15) - Question 26
Ritesh got an extra amount of Rs 730 - 680 i.e. Rs 50 on his second investment instrument.

The interest earned in the first year (on each of the investment instrument) = 680/2 = 340.

⇒ Rate of interest = (50/340) x 100 = 14.70%

⇒ 14.70% of his money invested in one of the bonds = Rs 340

⇒ Total investment in one of the bonds = (340/14.70) x 100 = Rs. 2313

⇒ His total investment in two bonds = 2313 x 2 = Rs 4626

CAT Mock Test - 13 (November 15) - Question 27

What is the remainder when x276 + 12 is divided by x2 + x + 1 for x >3?


Detailed Solution for CAT Mock Test - 13 (November 15) - Question 27
Let's say the remainder is R.

x276 + 12 = (x2 + x + 1)f(x) + R

Now, w and w2 (Cube root of unity) are the roots of x2 + x + 1.

⇒ w2 + w + 1 and w4 + w2 + 1 both will be zero.

⇒ w276 + 12 = R

Or, R = 1 + 12 = 13 (w3 = 1)

CAT Mock Test - 13 (November 15) - Question 28

Mr. Yarn owns a fabric store. He sells his cloth 40% above the wholesale price he pays. One day he discovers that the meter stick has been using to measure the cloth he sells is not exactly a meter. Because of this error, he is only earning a 39% profit. Approximately how long is Mr. Yarn's faulty meter stick? (Note that he uses the meter stick only to sell cloth; the amount he buys is correct)

Detailed Solution for CAT Mock Test - 13 (November 15) - Question 28
Let CP for 100 cm cloth be Rs. 100.

SP = 140 for P cm of cloth. The CP for P cm of cloth will be P

We have (140 - P) x 100 = 39P

Or, P = 100.7cm.

CAT Mock Test - 13 (November 15) - Question 29

2z = (0.2)w = 1000. Then the value of [(1/z) - (1/w)] is

Detailed Solution for CAT Mock Test - 13 (November 15) - Question 29

2z = (0.2)w = 1000

2z = 1000

2 = 103/z (i)

(0.2)w = 1000

(0.2)w = 103

0.2 = 10(3/w)

2 = 10(3/w +1) (ii)

So from (i) & (ii)

103/z = 10 (3/w +1)

3/z = 3/w + 1

So 1/z - 1/w = 1/3.

CAT Mock Test - 13 (November 15) - Question 30

A work is done by three persons A, B and C. A alone takes 9 minutes to manufacture a single bolt, while B and C working together take 6 minutes to manufacture a single bolt. If the entire task requires manufacturing of 30 such bolts, and all three work together, then how many minutes does the trio need to work for?


Detailed Solution for CAT Mock Test - 13 (November 15) - Question 30
A alone takes 9 minutes to manufacture a single bolt, hence in 1 minute, 1/9th of a bolt is manufactured.

B and C working together take 6 minutes to manufacture a single bolt, hence in 1 minute, 1/6th of a bolt is manufactured.

If all three start working together, then in 1 minute, they can manufacture (1/9 + 1/6)th of a bolt or 5/18th of a bolt,

Hence 1 bolt takes the trio 18/5 or 3.6 minutes to manufacture.

Thus 30 bolts will take the trio 30*3.6 = 108 minutes to manufacture.
